The touchscreen driver s3c2410_ts.c doesn't work well when using the tslib, an abstraction layer for touchscreen panel events. Tslib needs ABS_X ABS_Y and ABS_PRESSURE events to report, but only the former two the driver can provide.It seems much more sane to fix this in tslib, the kernel is not actually reporting pressure meaningfully here and there's already BTN_TOUCH to report if the pen is down.
yeah,I will try to fix it in tslib. Thanks a lot.
